[Tex/LaTex] Onecolumn without page break

two-column

How can I make a one column in a two column article, without page breaking???

I am writing an article to submit to NIM. The article should be 2 columns.
In one of the pages I need to put a wide figure at the top of the page, and then continue with 2 column text, like in the attached Screenshot_1.png…

But the way I am trying this, latex puts the 2 column continuation to a new page…

Is this possible in Latex without page break?

This is how I try:

\documentclass[12pt]{elsarticle}

\journal{Nucl. Instrum. Methods A}

\begin{document}

\begin{twocolumn}

   bla, bla, bla

\end{twocolumn}

\onecolumn

\begin{figure}[t]

\begin{center}

\includegraphics[width=17.4cm]{pic/RESULTS_SUM.pdf}

\label{Si_Results}

\end{center}

\end{figure}

\begin{twocolumn}

   bla, bla, bla,

\end{twocolumn}

\end{document}

If you want to set the entire text in two column, then give the number of columns in class option, please avoid to keep \begin{twocolumn}..., example given below:

\documentclass[twocolumn,12pt,3p]{elsarticle}
\usepackage{lipsum}
\journal{Nucl. Instrum. Methods A}

\begin{document}

\title{Article title}

\author{Author Name}

\begin{abstract}
\lipsum[1]
\end{abstract}
\maketitle

   bla, bla, bla

\lipsum[1-8]

\begin{figure*}
\centering
\includegraphics[width=17.4cm]{example-image-a}
\label{Si_Results}
\end{figure*}

\lipsum[1-8]

\end{document}

In general, any floats are not allowed in first page of an article...

The dual title in twocolumn mode causes the page breaks. Perhaps you'd just be interested in setting the title manually. Below I've taken the \maketitle constructions from the titling package code:

enter image description here

\documentclass[twocolumn]{article}
\usepackage{lipsum}% Just for this example
\begin{document}

\twocolumn[{
\begin{center}
  \LARGE First title
\end{center}
\vskip 2em
\begin{center}
  \large \lineskip .75em%
  \begin{tabular}[t]{c}
    Author1, Author2
  \end{tabular}\par
\end{center}
\begin{center}
  \large \today
\end{center}

\vspace{2\baselineskip}

\begin{center}
  \LARGE Second title
\end{center}
\vskip 2em
\begin{center}
  \large \lineskip .75em%
  \begin{tabular}[t]{c}
    Author1, Author2
  \end{tabular}\par
\end{center}
\begin{center}
  \large \today
\end{center}
}]

\lipsum[1-5]
\end{document}

You can now adjust the spacing and font to your liking.

I suggest using the multlined environment from mathtools to break the radicand . You also can choose not to break it, but to type in medsize (~80 % of \displaystyle) with the \mediummath command from nccmath. I took the opportunity to clean your code:

\documentclass[11pt,a4paper,twocolumn]{article}
\usepackage[utf8]{inputenc}
\usepackage{mathtools, nccmath}

\begin{document}

\begin{equation*}
    \bigl| \dot{r} \bigr| =
    \sqrt{\begin{multlined}[b] -\!\bigl(e^{-t} ( \cos t + \sin t )\bigr)^2 + \\ \bigl(e^{-t} (\cos t + \sin t)\bigr)^2 + \bigl(-e^{-t}\bigr)^2 \end{multlined}}
\end{equation*}
\begin{align*}
    \bigl| \dot{r} \bigr| & =
    \sqrt{\medmath{ -\!\bigl(e^{-t} ( \cos t + \sin t )\bigr)^2 + \bigl(e^{-t} (\cos t + \sin t)\bigr)^2 + \bigl(-e^{-t}\bigr)^2}} \\
         & = \sqrt{ -\!\bigl(e^{-t} ( \cos t + \sin t )\bigr)^2 + \bigl(e^{-t} (\cos t + \sin t)\bigr)^2 + \bigl(-e^{-t}\bigr)^2}
\end{align*}

\end{document}
